They are extremely soft, generously sized at 12x16", effective cleaners for most surfaces, soak in a lot of liquid and are also known as the microfiber cloths. With so many coming in one set of white, blue and yellow colours, you have all of your house and even garden covered!
I remember feeling quite frustrated with my cotton cloths which I'd need to squeeze really hard to get all the water out, and they would still leave traces of water behind - plus they used to smell! Ever since this wonderful material has been invented, keeping my house spotless has become effortless and I don't even have to use harsh chemicals anymore since they do the job so well with mild eco-friendly ones.
If you have a house which requires a lot of cleaning than this is a fantastic time and money saving buy!
